Motuihe Island Public Toilet Installation

Motuihe Island has some of the best sandy beaches of the inner Hauraki Gulf islands, and these, together with its clear waters, sheltered anchorages, visitors facilities and community conservation efforts, make it a popular destination for day visits and camping. 

The Department of Conservation (DOC) manage the island facilities, and were the Principle for this project. DOC called for tenders for the replacement of the existing failed commercial sized on site wastewater treatment system that services the existing public toilets on the island with difficult site access. Reflection Treatment System Ltd provided the winning design for this project, offering the most favourable solution in terms of cost, high environmental standards and ease of construction and maintenance. 

Owhanake Wastewater Treatment Plant

The Auckland City Council put out a request for tender for the design, build and operation of a Recirculating Sand Filter system required to treat commercial strength wastewater from Oneroa Township, located on Waiheke Island in the Hauraki Gulf. A Cluster Wastewater Management System was required to address the sewage problems arising from the increased development the in Oneroa Township. The wastewater treatment plant includes holding tanks to account for the variable flows, a recirculating sand filter, slag filter, nutrient reduction, with further treatment via natural and manmade treatment wetlands and disposal to a waterway. The Treatment Plant is monitored and controlled via remote telemetry, and is tested for chemical and biological performance on a monthly basis.

Park View Retirement Village

Park View Village in Tapu Road, Huapai was designed, constructed and marketed by Universal Homes for a niche market of independent retired people. Our role was to design, install and manage the Wastewater Treatment and Disposal, which was ten metres from homes, without visual or odour intrusion, and which could be managed without worry to the owners.

The Sands

The Sands is a high-quality subdivision at the Northland beach township of Mangawhai Heads. The subdivision was staged to match market demand and also to phase the development costs. The reticulation and treatment system were also staged for the same reasons. A Reflection Bottomless Sand Filter was chosen due to its low cost, with a high level of treatment (including Coliform removal) and providing the technology best suited for highly variable, seasonal loading rates. The Kaipara District Council is planning to connect the whole town to a centralised sewer system. The reticulation was therefore installed to suit current on-site treatment and any subsequent township system.
